  - Where it differs is the ability to use one REGEX string to match many strings.
    - i.e, the REGEX "`abc\d+`" will match with "`abc1`", "`abc2`", "`abc12`", but not "`ac12`" or "`abc`".
  - Many characters can be used as normal and will match a string literally (character for character), but some will be treated as special characters (such as the previously used `\`, which indicates that the letter afterwards should be treated specially, such as a token)
-   - Common tokens to be aware of: `.` for any character, `\d` for single digits, `\w` for word characters, `\s` for space characters (tabs, spaces, linebreaks, etc.). Tokens can be repeated by using `+`, indicating "one or more", `*` indicating "none or more".
+   - Common tokens to be aware of: `.` for any character, `\d` for single digits, `\w` for word characters, `\s` for space characters (tabs, spaces, linebreaks, etc.). Tokens can be repeated by using `+`, indicating "one or more", `*` indicating "none or more". If you want to match something that is read as a token by default, such as `.`, or `+`, using the `\` in front of it will cause it to match `.` literally, i.e, `1\.2` matches `1.3`, but not `123`, `1a3`, etc.
  - A capture group is a way of "selecting" a part of a text and is formed by using `(` and `)` around the REGEX that should be selected.
 
  Now for a few examples:
 
-Let's say we have files `run325-a-1.vcf`, `run326-b-2.vcf`, and `run327-b-3.vcf`. If we know that all that matters is the `1` after the `run[numbers]-[character]-`, we can write `run\d+-\w-(\d).vcf` which will match with all 3 of the above examples, and select the last digit. The program can then use a given CSV to look up the selected digits and replace the name with what is given by the CSV.

 For learning and testing your own REGEX, checkout [regex101.com](https://regex101.com/), which allows you to write the strings that you're trying to match, and the REGEX. It will show you live which parts of the strings match to what, if any parts match.
